Dirty or clogged condenser coils can reduce heat transfer and increase energy consumption. Regular cleaning and inspection are essential. Again, consult your Dalmec refrigeration instructions for specific cleaning procedures and maintenance schedules.
  • Evaporator: The evaporator is where the low-pressure liquid refrigerant absorbs heat from the refrigerated space, causing it to evaporate into a low-pressure gas. This process cools the air or product in the refrigerated space. Dalmec evaporators are designed for efficient heat transfer and come in various configurations, such as finned coils and plate heat exchangers. Proper airflow across the evaporator is essential for optimal performance. Blocked or restricted airflow can reduce cooling capacity and increase energy consumption. Regular inspection and cleaning of the evaporator coils are necessary. Check your Dalmec refrigeration instructions for recommended cleaning agents and procedures.
  • Expansion Valve: The expansion valve controls the flow of refrigerant into the evaporator, reducing its pressure and temperature. This allows the refrigerant to absorb heat and cool the refrigerated space. Dalmec uses various types of expansion valves, including thermostatic expansion valves (TXVs) and electronic expansion valves (EEVs). TXVs are mechanically controlled and adjust the refrigerant flow based on the temperature of the evaporator outlet. EEVs are electronically controlled and offer more precise control over refrigerant flow. Proper adjustment of the expansion valve is crucial for optimal performance. An improperly adjusted expansion valve can lead to reduced cooling capacity, increased energy consumption, and even damage to the compressor. Consult your Dalmec refrigeration instructions for proper adjustment procedures.
  • Control System: The control system monitors and controls the various components of the refrigeration system, ensuring optimal performance and safety. Dalmec control systems often include temperature sensors, pressure sensors, and electronic controllers. These components work together to maintain the desired temperature and humidity in the refrigerated space. Understanding the control system is essential for troubleshooting problems. The control system can provide valuable information about the system's performance and identify potential issues. Always refer to your Dalmec refrigeration instructions for information on how to use and troubleshoot the control system.
